PAINTING APPARATUS.

Specification of Letters Patent.

Patented July 25, 1905.

Application filed March 21, 1905. Serial No. 251,273.

1'0 alt w/wm/ it may concern:

Be it known that we, CHAnLns M. HAESKE and AXEL W. J OI-INSON, citizens of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented new and useful Improvements in Painting Apparatus, of which the following is a specification.

The invention comprises certain new and useful improvements in painting apparatus, and is designed more especially for use in connection with the spindle mechanism of an apparatus which holds the work during the operation of dipping, striping, &c.

The object of the invention is to provide a device which will effectively overcome the resistance caused by the paint taken up adher ing to the spindles.

In the drawings, Figure 1 is a perspective View of a suspended wheel-jack, such as is shown in Patent No. 765,278, granted July 19, 1904, and having our present invention applied to the spindle thereof. Fig. 2 is a detail view of the spacing-ferrules and friction-disks. Fig. 3 is a sectional view of a slightly-modified form of friction-disk.

Like letters of reference refer to corresponding parts throughout the specification and the several figures of the drawings.

The apparatus disclosed in Patent No. 765,278,granted July 19, 1904:, is designed for use in connection with what is known as dip painting. .In using said apparatus the wheels are mounted on the spindles, and by means of an overhead railway they are conveyed to the dipping-tank, where the wheels while still mounted upon the jack are dipped. They are then conveyed to the drying-room and afterward are ready for the striping operation. In order to facilitate the striping operation, it is essential that the wheels be capable of being readily and easily rotated, especially so when the striping is to be done by hand, for the reason that in such case the rotation of the wheels must obviously be accomplished by one hand. It has been found that while the wheels are undergoing the dipping operation, the paint taken up by the hub-thimbles and the spindles of the jack is such as to cause so much friction between the said hub-thimbles and spindles as to prevent the free rotation of the wheels. To overcome this serious objection, we have devised the present combination of antifriction-disks and ferrules.

A designates generally a Wheel-jack, and a the spindles thereof.

B designates a vehicle-wheel hub provided with the usual hub-thimbles b.

O C designate, respectively, the outer and inner antifriction disks. These disks are preferably though not necessarily of iron and may have their peripheries inclined or rounded, as shown in Fig. 3 of the drawings. The outer disk 0 is of smaller diameter than the diameter of the inner disk 0, and each disk is provided with a central opening 0 c of such a size as to allow the jack-spindles to pass freely through them.

D D designate, respectively, the outer and inner spacing-ferrules, the outer ferrule being longer than the inner ferrule. The openings through these ferrules are of such a size as to allow of free rotation upon the jackspindles.

In assembling our antifriction device upon the jack-spindles the short ferrule D is first placed upon the spindle and is slid thereon until it is adjacent to the body portion of the jack. The larger friction-disk C is then slid upon the spindle until it is adjacent the short ferrule. Next the longer ferrule D is placed upon the spindle and slid down adjacent to the larger antifriction-disk C, after which the smaller antifriction-disk V is placed upon the spindle adjacent the longer ferrule. A'ny desired means may be employed for retaining these ferrules and antifriction-disks in position upon the spindles. As an example we have shown the well-known split key, which is passed through an opening or slot at the end of the spindle.

From the foregoing it will be seen that by varying the lengths of the ferrules used the distances between the two antifriction-disks will be varied to cause them to accommodate themselves. to the size of the hub-thimbles, and as both the antifriction-disks and the ferrules are capable of free rotation upon the spindles little or no resistance will be had to the free rotation of the vehicle-wheels.

We claim as our invention 1. An antifriction device forapainting apparatus comprising rotatably-rnonnted antifriction-disks and rotatably-mounted ferrules adapted to space the said disks the desired distance apart. v

2. An antifriction device for a painting apparatus comprising a pair of antifrictiendisks, one of said disks being'of larger diameter than the other disk, and ferrules of differentlengths, adapted to space the said disks the desired distance apart.

In testimony whereof we aflix our signatures in presence of two subscribing witnesses.
